Patent of the Week: Improving the Performance of Antibody Fragments
Patent-of-the-week-improving-the-performance-of-antibody-fragments
Antibody fragments, including Fabs, which bind to immune response-triggering substances, or antigens, have demonstrated utility in various research and diagnostic applications. However, their structure limits their use, so researchers have engineered a protein that can be tethered to Fabs to expand their functionality.
The inventors, including Anthony Kossiakoff, a professor of biochemistry and molecular …
